The application discloses a preparation method of a pollen composition with whitening and anti-wrinkle effects, a product and application thereof, and belongs to the technical field of compositions. The technical problem to be solved is to provide an active component with the double effects of whitening and anti-wrinkle, and the active component is extracted and the component is simple and stable. The technical solution is as follows: at least two or more of pine pollen, sunflower pollen, tea pollen and rose pollen are used as raw materials, the raw materials are physically crushed, then subjected to enzymolysis by using a composite cellulase, and then subjected to hot water extraction, so that whitening components and anti-wrinkle components are enriched, and the prepared pollen composition has excellent whitening effect and anti-wrinkle effect.

This invention, entitled "A Sunflower Pollen Fermentation Product, Its Preparation Method, and Its Application," belongs to the field of biotechnology. The technical problem to be solved is to improve the antioxidant, immunomodulatory, and intestinal protective capabilities of sunflower pollen. The key technical solution is the preparation method, which includes the following steps: adding sunflower pollen to a fermentation culture medium to obtain a fermentation substrate; inoculating the fermentation substrate with *Lactobacillus* for fermentation culture, separating the solid and liquid phases to obtain a supernatant; concentrating and drying the supernatant to obtain the final product. The *Lactobacillus* is selected from *Lactobacillus casei*, *Lactobacillus plantarum*, and *Lactobacillus rhamnosus*.

The application discloses a kind of nasal drops based on drug-loaded pollen for rhinitis and its preparation method and application, belong to the field of biomedical materials;The nasal drops include drug-loaded pollen microcarrier and pharmaceutically acceptable adjuvant;The drug-loaded pollen microcarrier is natural sunflower pollen particle with hollow cavity and surface thorn structure, and the cavity is loaded with the drug for treating allergic rhinitis.In the preparation method, sunflower pollen is washed, defatted with acetone diethyl ether, and treated with phosphoric acid cleavage to obtain pollen microcarrier with hollow outer thorn;Then, small molecule drugs are loaded under vacuum and reduced pressure;Finally, the adjuvant is mixed to prepare the drops.The application utilizes the natural "internal cavity and external thorn" structure of pollen, realizes efficient adhesion and sustained-release drug delivery in nasal cavity, and effectively resists cilia clearance.The pollen microcarrier removes allergenic proteins, has good biocompatibility, and does not aggravate allergic rhinitis.The application is low in cost and simple in operation, and provides a safe and efficient new platform for nasal drug delivery.

The invention discloses a water-control low-temperature collaborative preservation method for sunflower pollen, and relates to the technical field of agricultural biologication.The method comprises the steps that fresh and exposed male parent pollen is collected in the full-bloom stage of sunflowers, the male parent pollen is sieved to remove impurities, and pure pollen grains are obtained; putting the pure pollen grains into a closed container taking allochroic silicagel as a drying agent, and performing dehydration treatment for 2-3 hours in an environment of 15-25 DEG C to obtain dehydrated pollen grains; and sub-packaging the dehydrated pollen grains in a vacuum sealed container, and immediately transferring the pollen grains to a low-temperature environment of-18 DEG C to-20 DEG C for vacuum freezing storage to obtain the frozen and preserved active sunflower pollen preparation. And during pollination, taking out the cryopreserved active sunflower pollen preparation, standing and unfreezing for 2-4 hours at room temperature, and pollinating the sunflower female parent stigmas after the temperature is recovered to the room temperature. The sunflower pollen preservation method is excellent in preservation effect, low in cost, large in storage capacity and safe, simple and convenient to operate.

The invention belongs to the technical field of lithium ion battery electrode materials, and particularly relates to a nitrogen-phosphorus-doped porous blocky C-coated ZnO material and a preparation method and application thereof.The preparation method comprises the steps that sunflower pollen is added into deionized water to be subjected to ultrasonic and room-temperature stirring treatment, suction filtration and cleaning are conducted after treatment, and sunflower pollen particles serving as a carbon precursor are obtained; adding zinc chloride into deionized water, stirring to enable the zinc chloride to be fully dispersed, adding sunflower pollen particles, continuously stirring, dropwise adding a sodium hydroxide solution, continuously stirring for reaction after dropwise adding, and filtering and drying after reaction to obtain a reaction precursor; in an argon atmosphere, heating the reaction precursor from room temperature to 550-650 DEG C, preserving heat for 2-4 hours, and calcining; and after calcining, naturally cooling to room temperature to obtain the nitrogen and phosphorus doped porous blocky C-coated ZnO material. The raw materials are easy to obtain, the preparation method is simple, and the problem of poor cycling stability of the zinc oxide / carbon composite material is solved.
